Overlay ?

comment:2 by ekdahl, 17 years ago

I'm using vesa driver, so I wouldn't think so.

comment:3 by stippi, 17 years ago

What if the OpenGL is trying to grab a direct window lock and does not get it while the screen shot is being taken? Interesting bug, certainly.

Can't reproduce with a Radeon graphics card and GLTeapot. Which app are you using ? Is it real hardware ?

comment:5 by jackburton, 17 years ago

Are we reading the front buffer or the backbuffer when taking the screenshot ?

Replying to korli:

It happens with GLDirectMode and GLTeapot for example. It's on real hardware. Also see ​http://www.haiku-os.org/blog/tangobravo/2008-02-05/haiku_activity_update_4_9_september_2007_5_february_2008#comment-8490 Obviously it also happens for Philippe.

Could you check again ? Stephan did some changes on the buffering. Be sure to give the tested revision. Thanks.

comment:8 by ekdahl, 17 years ago

Still the same problem in hrev24145.

comment:9 by korli, 17 years ago

VESA mode ?

comment:10 by ekdahl, 17 years ago

1280 x 1024 x 16/32 (32 after the default changed)

comment:11 by korli, 17 years ago

Could you check against hrev24346 please ?

comment:12 by ekdahl, 17 years ago

Yes, I'll test as soon as I get a build system up and running again.

comment:13 by stippi, 17 years ago

No need, the output is still mysteriously missing from screenshots. Have no time to look into it right now.

comment:14 by kaoutsis, 17 years ago

with hrev25221 and intel_extreme i got these nice screenshots (see attached GLDirectMode-screenshot-intel-extreme-hrev25221.png and GLTeapot-screenshot-intel-extreme-hrev25221.png resolution is 1440x900 and 32 bits/Pixel

further testing: i switch to 16 bits/Pixel from 32 bits/Pixel and run again GLDirectMode and GLTeapot: the screenshots for both apps have only a black window now.

comment:16 by korli, 17 years ago

Could you check again please (hrev25952+) ?

comment:17 by ekdahl, 17 years ago

Haiku isn't bootable for me ATM, so I can't test it. But it should be easy for anyone to test it using vesa driver.

comment:18 by korli, 17 years ago

Resolution: → fixed
Status: new → closed

Should be fixed. Please reopen if needed.

comment:19 by ekdahl, 16 years ago

Yes, I can confirm that it works here too.
